Yeoman Excel Addin - Certificate Issue

When trying to run the example from the Excel Addin Tutorial (https://learn.microsoft.com/en-us/office/dev/add-ins/tutorials/excel-tutorial#prerequisites), I get an error.

Inside Excel - Content blocked - there is no valid certificate

I also check at https://localhost:3000 and in fact, there is no valid certificate.

The npm start doesn't ask for the certificate installation. How can I do please?

Solution

  • The certificate (ca.crt) was in C:\Users\%username%\.office-addin-dev-certs.
